Hi, Great Tutoial, i have a problem in converging the distillation column (i'm getting : Fatal Error - Zero Diagonal in Column Matrix) Message and the column doesn't converge ! That's for a Dumping Factor of 1. While i change the dumping factor to 0.5 the column rapidly converges ! What is your explanation for this ? is it because the distillation column in this case is Highly non Ideal ?
@@Chemiopedia Thanks a lot. Waiting for the next Tutorials. I hope you'll teach us some of the Economic aspects of processes using Aspen Process Economic Analyzer and some get into rigorous modeling of all Heat Transfer Equipments in HYSYS.
Can you send me the research paper from where you have taken this simulation.

Yes it's highly non ideal.
You can also converge the column with dumping factor 1 if you have some guess values of column temperatures

if we want to obtain Nitrogen than what?
sir can you help me with my btech project ..its lng producction by cryogenic distillation
